1. AI Avatars and Talking Avatars
シンセシス: Synthesys gives you AI humans and lifelike avatars to present a script. You can generate avatars that look polished for ads and e-learning. The avatar library is broad enough for most marketing videos.

した: D-ID uses Creative Reality technology to build realistic talking avatars from photos. You can upload images and create avatars that move and speak. The result is lifelike avatars with natural facial motion.

2. AI音声とテキスト読み上げ
シンセシス: This is where Synthesys shines. It offers over 300 voices in 140 languages for text to speech. The tool is built for generating realistic voices that sound human in many languages.

した: D-ID covers a solid standard voice set for its avatars. It is enough for talking avatars and chatbots. But it does not match the extensive library Synthesys offers for voice work.
3. Video Creation from Text
シンセシス: Synthesys handles full video creation from a script. Type your text and the tool will generate videos with an avatar and voice. It is aimed at complete video generation for commercial use.

した: D-ID focuses on photo-to-video conversion. You upload a face and add a script, then it creates a short talking clip. It is less about long-form video and more about quick avatar videos.

4. Talking Photos and Image Animation
シンセシス: The AI Talking Photos tool brings static images to life. Upload a picture and it speaks your script. This is a fun way to create video content from a single image.

した: Photo animation is the core of D-ID. Its Talking Head API turns any face into a moving avatar. This is the feature developers use most for interactive experiences.

5. 多言語サポートと翻訳
シンセシス: Multilingual support is a strong point. With 140 languages, you can produce video content for global audiences. Audio translations let you reuse one script in multiple languages.

した: D-ID has multilingual support for global video content. Its Video Translator swaps the spoken language while keeping the avatar in sync. This helps brands reach viewers in multiple languages.

6. Real-Time AI Agents
シンセシス: The Synthesys Lab adds experimental tools for creators. But Synthesys does not offer live, real-time avatar chat. It is built for pre-rendered video, not live conversation.

した: D-ID AI Agents allow real-time avatar conversations through chatbots. A visitor can talk to a talking face on your site. This is the clearest gap between the two platforms.

⚠️ 警告: If you need a chatbot with a talking face, only D-ID offers that. Synthesys cannot replace it here.
7. Media Generation and Templates
シンセシス: Generate AI Media lets you make images and audio in one place. With ready video templates, you can start creating stunning videos faster. These cool features speed up content for ads and social posts.

した: Video Campaigns help you produce many avatar clips from one setup. It is handy for personalized アウトリーチ at scale. The focus stays on avatar-led video rather than broad templates.

8. 統合とAPI
シンセシス: The Face form tool keeps avatar setup simple inside an intuitive interface. Synthesys leans on its own studio rather than deep developer hooks. It suits creators who work inside one app.

した: D-ID Integrations and a powerful API let you add photo animation to your own apps. Developers use it to build avatar features into websites and software. This is its biggest edge for product teams.

9. Audio Translation and Expression Control
シンセシス: Audio Translations convert a finished video into other languages. You can fine tune the voice and pacing. This keeps one video useful across multiple languages and markets.

した: Emotion and Expression Control lets you adjust how the avatar reacts. You can fine tune a smile or a serious tone. This adds realism to talking avatars in interactive experiences.

| 高い | 月額69ドル(ビジネスプラン) | 月額108ドル(アドバンスプラン) |
| 企業 | — | カスタム価格設定 |
シンセシス: Synthesys costs more to start at $20/month. For that, you get a deep voice and avatar studio. It is fair value if voice cloning and video creation are your main needs.
した: D-ID is far cheaper to enter at $4.7/month and has a free plan. The catch is the strict minute cap. Heavy users may hit limits and jump to the $108 Advanced plan.
